A typical example would be to pay investors a preferred return before paying any additional split to the sponsors.Think of fees as one off (acquisition, disposition), fixed (asset management) and variable, based on performance (the promote).

Since NNN deals are flat and passive is it common for the sponsor to take a promote?

All these comments promoting socialist style landlording, I say with absolute certainty they have 0 experience landlording or near to 0, because anyone with even novice level holdings and experience would never chastise someone for seeking fair market rents and offering a person a considerable discount from fair market in empathy for a 2decade+ rip-off that ran un-checked.

If they are brand new syndicators, I'd expect to see a lower GP promote/fees.

As noted, there are are the ones that just throw it on the MLS and sit back, and then there are those who actively promote it through a variety of other means they (should have) at their disposal...

(@Joshua Dorkin   I am assuming it is OK to promote going Pro on this site.)

@Rebekah Hitt, I've seen ROIs for LPs promoted from 6% or 8% for conservative institutional investments to 15% and higher IRRs, especially a few years ago. 

@Jarrett FogelmanSince you cannot self promote on BP.

Most of these "systems" or "programs" are just rebranded and likely created by dozens of other promoters and gurus. 

LLCs are wildly over promoted, much of that promotion shamelessly panders to folks fear, ignorance and vanity.
